IPC: B61D17/10
Filed: 2003-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To sufficiently secure an effective space in a driver's cab by efficiently absorbing impact energy not only when vehicles with each other come into a head-on collision but also when a certain obstacle collides against a position higher than an underframe of the vehicle.  <P>SOLUTION: In this railway rolling stock provided with the driver's cab, a member for constituting the floor of a driving cab 100 of the driver's cab is a buffer floor 110. The buffer floor 110 is constituted of a plurality of extrusion members 111, 112 and 113 having a plurality of hollow parts. The hollow members are arranged toward the longitudinal direction of a vehicle body in the extruding direction. The buffer floor 110 is arranged on an upper part of the height of the underframe of the vehicle. When a front end of the buffer floor 110 collides against an other vehicle, the buffer floor 110 is deformed into a bellows shape to absorb impact energy. When the front end collides against an anticlimber on a lower side of the vehicle, a box type buffer 155 is deformed into a bellows shape to absorb larger impact energy.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Filed: 2003-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a structure capable of reducing a weight and a space of a cloth printer superior in stability.  <P>SOLUTION: This printer comprises a medium conveyance section C to which a cloth can be set, a fixed side structure body S supporting the medium conveyance section C, and a head 5 for printing on the cloth. When a power source of the printer is in an OFF state, the medium conveyance section C is positioned to be involved in a part having a length Ls of the fixed side structure body in the moving direction of the medium conveyance section C (a housing position). When the cloth is set to or removed from the medium conveyance section C, the medium conveyance section C is positioned so that a part of the medium conveyance section C is projected to one side from the part having the length Ls (a cloth setting/removing position). When the operation of printing on the cloth is performed, the medium conveyance section C is controlled to be moved from the position where the part is projected to the one side (the cloth setting/removing position) to a position where the part is projected to the other side (a printing previous position), and then the medium conveyance section C is returned again to the position where the part is projected to the one side (the cloth setting/removing position).  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Title: Traverser for vehicle
Inventor: KAGEYAMA AKIRA
IPC: B66F7/28
Filed: 2003-03-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a lifting traverser with high safety capable of preventing persons and articles from accidentally falling to a pit.  <P>SOLUTION: Two lifters 4, 5 positioned immediately below and outside a running path of a vehicle are arranged to a pit 3. A conveying stand 7 is selectively put on both of the lifters 4, 5, and when both of the lifters 4, 5 are fully lowered, the conveying stand 7 can be re-put on both of the lifters 4, 5.
